Arsene Wenger saw off competition from Liverpool to land the Chile forward, who can play both in central and wide areas, for a fee thought to be in the region of £35million.

Sky Sports pundit Carragher is frustrated the player did not choose to join his former club and wonders if the signing will restrict the development of some of Arsenal’s England internationals.

“I think it’s a great signing for Arsenal,” he told Sky Sports News.

“I’m disappointed he hasn’t chosen Liverpool. I thought he may have become involved with the Luis Suarez deal, so it’s a blow for Liverpool to lose Suarez and miss out on him.

“He’s a great signing for Arsenal and he’s something that they need as well. I’m not sure where he’s going to play because I don’t think he’s an out-and-out centre forward.

“It may impact on Theo Walcott and Alex Oxlade-Chamberlain, we’re talking about young English players, but his predominant position for Barcelona is in the wide areas.

“For Chile, he played through the middle and he could do that, but I don’t think he’s an out-and-out centre-forward and that may have an impact on Walcott and Oxlade-Chamberlain getting in the Arsenal team.”

Sanchez is set to make his Premier League debut against Crystal Palace live on Sky Sports on the opening day of the new campaign, with all last season’s top four to be shown live on the first weekend.

Sky Sports has confirmed it will show Liverpool’s first five games of the campaign and Carragher says his old side is set for a tough start, although he expects them to beat Southampton on the first Super Sunday having signed Rickie Lambert and Adam Lallana, whilst also being linked with Dejan Lovren.
